IWN(4) FreeBSD Kernel Interfaces Manual IWN(4)
NAMEiwn -- Intel Wireless WiFi Link 4965/5000 IEEE 802.11n driver
SYNOPSIS
To compile this driver into the kernel, include the following lines in
your kernel configuration file:
deviceiwndevicepcidevicewlandevicefirmware
You also need to select a firmware for your device. Choose one from:
deviceiwn4965fwdeviceiwn5000fwdeviceiwn5100fw
Or you can use
deviceiwnfw
to include them all.
Alternatively, to load the driver as a module at boot time, place the
following lines in loader.conf(5):
if_iwn_load="YES"
iwn4965fw_load="YES"
iwn5000fw_load="YES"
iwn5100fw_load="YES"
DESCRIPTION
The iwn driver provides support for Intel Wireless WiFi Link 4965 and
5000 series of PCI-Express network adapters. iwn supports station,
adhoc, and monitor mode operation. Only one virtual interface may be
configured at any time. For more information on configuring this device,
see ifconfig(8).
This driver requires the firmware built with the iwnfw module to work.
EXAMPLES
Join an existing BSS network (i.e., connect to an access point):
ifconfig wlan create wlandev iwn0 inet 192.168.0.20 \
netmask 0xffffff00
Join a specific BSS network with network name ``my_net'':
ifconfig wlan create wlandev iwn0 ssid my_net up
Join a specific BSS network with 64-bit WEP encryption:
ifconfig wlan create wlandev iwn0 ssid my_net \
wepmode on wepkey 0x1234567890 weptxkey 1 up
Join a specific BSS network with 128-bit WEP encryption:
ifconfig wlan create wlandev iwn0 wlanmode adhoc ssid my_net \
wepmode on wepkey 0x01020304050607080910111213 weptxkey 1
DIAGNOSTICSiwn%d:devicetimeout The driver will reset the hardware. This should
not happen.
iwn%d:firmwareerror The onboard microcontroller crashed for some rea-
son. The driver will reset the hardware. This should not happen.
iwn%d:timeoutwaitingforfirmwareinitializationtocomplete The
onboard microcontroller failed to initialize in time. This should not
happen.
iwn%d:couldnotloadfirmwareimage'%s' The driver failed to load the
firmware image using the firmware(9) subsystem. Verify the iwnfw(4)
firmware module is present.
iwn%d:couldnotloadbootfirmware An attempt to upload the boot
firmware image to the onboard microcontroller failed. This should not
happen.
iwn%d:couldnotloadmicrocode An attempt to upload the microcode image
to the onboard microcontroller failed. This should not happen.
iwn%d:couldnotloadmainfirmware An attempt to upload the main
firmware image to the onboard microcontroller failed. This should not
happen.
